DRYING PLANT FOR BRICKS.

SPECIFICATION formng part of Letters Patent No. *770,186, dated. September 13, 1904.

Application filed December 29, 1903. Serial No. 186,93l. (No model.)

To cZl whom it may conccrn:

Be it known that I, GUSTAV PAGEL, a citizen of the German Empire, residing at 16 Alexander street, Stettin, Germany, have invented certain new and useful Improvements in the Construction of Drying Plants 'or Bricks, of which the following is a specification.

My invention relates to improvements in the Construction of drying-compartments as part of a brick-making plant; and its object is to make use of waste heat in the process of drying bricks and to avoid a cracking of the latter.

My improved Construction is illustrated by the drawings herewith, in which Figure l is a plan view, partly in section, of a portion of a brick-kiln and the dryingcompartment and air-conduits. Fig. 2 is a vertical cross-section of the new Construction on the line A B of Fig. l; Fig. 3, a vertical longitudinal section of the kiln portion of Fig. 1; Fig. 4, a cross-section of the same on the line C D of Fig. 3; and Fig. 5, a section of the drying plant on line EF of Fig. 2, With a plan elevation of the rail-basement.

As the drawings show, the smoke escape from the kiln to the drying-chamber is provided at the bottom of the Construction, the smoke-Conduit S being laid below the bottom of the drying-compartment, following the same along and terminating in a chimney Sci. Two lateral conduits Z feed the drying-compartment With dry andhot air. The conduits A draw the air oil" from the compartment, join the smoke-conduit S, and terminate With the latter in the chimney SCL. Both the said conduits A and the portions of the air-suppliers Z which are under the dryng-compartmentis are provided with sliding plates a I to regulate the admission and exit of the air. The position of the said sliding plates is shown by Fig. 5. Radiators c, 'ed by waste steam from the steam-engine of the establishment, are also provided. The air, which is heated by passing through the kiln after the burned bricks have been removed therefrom, is conducted to the drying-compartment through the aforesaid feeding-conduits Z, the quantity of the hot air to be admitted being regulated In the drying structure the hot air ascends and diffuses in the drying-room, the moisture in this room coming from the bricks piled therein mixing with the dry air. When the mixture is sufi icient, the air impregnated with moist vapors is drawn off through the aforesaid conduits A, provided on the outsides of the two feeding-conduits Z and terminating in the chimney, as aforesaid. The sliding plates a regulate the exit of the air, just as its admission is controlled by the sliding plates b. The exit of the air is favored by the provision of the conduits A on the outside, which permits the air to precipitate its moisture in these conduits. The moisture collecting in the discharge-conduit may be conducted to a basin f in any suitable way. Between each two sliding plates in the discharge-conduit there is a gap in the walls w w, upon which are mounted the rails that Carry the brick-carriages w', (see Fig. 5,) so that the moist air only is drawn to the aperture of the discharge-conduit A, and at the same time the air impregnated by the moist vapors combines With the hot air of the feed-Conduit and the radiators, entering through the said openings in the walls which support the rails, thus moistening the dry air and obviating a cracking of the bricks by prote'cting them from the approach of too hot or dry air. To eliminate the hygroscopic water of the bricks, the latter are'heated by radiators L, placed near the exit of the drying-compartment and 'ed direct from a steam-engine. The heating and desiccating process is supported by the escaping smoke being conducted just below the drying-compartment, from which it is separated by a dome of cast-iron. The drying-compartment is shut off against the outside at both ends by tightly-closing sliding doors, which are opened for the feedingthe room with bricks and for the discharge of the latter. These doors are-comnonly employed in drying-compartments, and I have therefore not shown the same, as their construction and location are well understood.

The brick-burning kiln is shown in top plan view at the upper part of Fig. 1, in vertical longitudinal section in Fig. 3, and in transverse vertical section in Fig. 4: and contains the burning-chamber B, which extends along IOO both sides of the k'l'n and across the end of the kiln adjacent to the drying-cornpartment. The chamber B communicates With the conduit S by a lateral passage e', which is controlled by a valve e, and the ehamber B also eommunicates With the conduit s Z Z by passages d d', which are controlled by valves d d, the stems of Valves d d and e projecting through the top of the burning-kiln, as shown in Figs. 3 and 4.

What I claim a s new, and desre to secure by Letters Patent, is-

In a plant for drying bricks, the combinetion of a kiln, a dryng-cornpartment communcating With said kiln a smoke-Conduit opening into the kiln' and extending l'engthw'se under said compartment, supplementary con- GUSTAV PAGEL.
